Microsoft released version 1.0 of Microsoft Security Essentials, a free basic anti-malware service from Redmond, on Tuesday. This replaces Microsoft’s discontinued Live OneCare Security-as-a-Service offering. Live OneCare customers can move to Microsoft Security Essentials once their subscriptions expire. Microsoft Security Essentials is a lightweight application that runs in the background and takes up few CPU and memory resources, the vendor said. It is the first Microsoft security product to use the company’s new Dynamic Signature Service.
